# Joining using a Link invitation (Guest/Ad-Hoc)

This method is for when the host only sends you a direct link. Since the Pico VR browser does not easily launch VR apps from web links, you must first register the link using a helper device or manually enter the URL.

**Prerequisites:**

- The host sends you the invitation link via email or chat.
- You must access the link on a **PC or mobile device** (Method A) or manually type it in VR (Method B).

#### Method A: Registering the Link to Your Account (Recommended)

Use a PC or mobile device to register the link, which converts the invitation into a registered session, allowing the Pico headset to treat you as an invited contact.

**Action (on PC/Mobile Device):**

1. **Click the Invitation Link** provided by the host on your **PC or Mobile Device**.
2. On the web page that opens, click the **Add to Calendar** or **Add Link** button.
3. **Log In:** If prompted, log into your **SimLab account**.
4. The session is now registered in the **Invitations** tab on the **SimLab Dashboard**.

**Joining the Session (in Pico VR Headset):**

1. Put on your **Pico VR Headset** and launch the **SimLab VR Viewer** while logged into the same account.
2. Because the session is registered to your account, when the host starts the session, you will receive the **in-app notification** (as described on Page 2).
3. Click **Join** to enter the **Lobby**.

#### Method B: Joining via the URL Launcher (Manual Input)

This method lets you bypass the web registration by entering the link directly in the VR Viewer.

**Action (in Pico VR Headset):**

1. Launch the **SimLab VR Viewer** application.
2. Locate and click the **URL Launcher** button (often a small icon or button).
3. Use the VR keyboard to **type or paste the Invitation Link** into the dialogue window.
4. Click **Confirm**.

**Result:**

- You will be taken to the **Lobby** screen where the VR experience will load, and you can join the session. If you were not already signed in, you may be prompted to **Login** or **Continue as a Guest**.
